Mountain Bike Rear Shock 120mm-200mm - Hydraulic MTB Rear Suspension

In this review of the CNCLOL Mountain Bike Rear Shock the bottom line is simple: this hydraulic rear suspension is a budget-friendly replacement for riders who need a straightforward upgrade to improve rear-end control. It is aimed at mountain bikers, e-bike and BMX modifiers, and scooter or DMN conversions who can match one of the offered eye-to-eye lengths and bushing sizes. The single biggest reason to buy is the oil pressure spring system that delivers a soft yet stable feel similar to air shocks but at a lower price point, making it a practical swap for many riders.

Key Features

• Application: Designed for MTB rear shock use, it fits mountain bikes, ebikes and several modified bikes so you can repurpose frames without exotic parts.
• Multiple lengths: Available in 120mm to 200mm eye-to-eye sizes so you can choose the shock that matches your frame mounting spacing.
• Load options: Rated for different loads (550lbs, 750lbs, 1000lbs) to help match rider weight and desired firmness for consistent performance.
• Oil pressure spring system: Provides soft, stable damping that mimics air shock behavior while aiming for longer service life and lower cost.
• Bushing size: Uses an 8mm x 24mm bushing that is a common fit for many rear shock mounts, simplifying installation for compatible frames.

Who It's For

This rear shock suits riders who need a cost-effective, hydraulic replacement for an OEM or worn rear shock on an MTB, electric mountain bike, BMX or a modified scooter and DMN builds. It is useful for hobbyists and commuters who want improved rear comfort and control without paying for high-end air shocks.

Riders who demand finely tunable damping, advanced rebound adjustment, or a factory-backed warranty should look elsewhere; this product is best for practical upgrades where fit and basic performance matter more than advanced features.

Pros & Cons

Pros

• Good value for money with a build that many customers report as solid and functional.
• Easy installation and fit for compatible mounts, making it a straightforward swap for common eye-to-eye spacing.

Cons

• Stiffness and rebound can be mixed depending on rider preference; some find it too stiff for plush trail use.
• Limited tuning compared with pricier air shocks, so riders wanting fine control may be disappointed.
